Alpine paleostress reconstruction and active faulting in Western Iberia [PDF]

open access: yesOpen Geosciences, 2010
The study of intraplate tectonics is crucial for understanding the deformation within plates, far from active plate boundaries and associated stress transmission to the plate interiors.

Morphological analysis of stylolites for paleostress estimation in limestones surrounding the Andra Underground Research Laboratory site [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences, 2013
We develop and test a methodology to infer paleostress from the morphology of stylolites within borehole cores. This non-destructive method is based on the analysis of the stylolite trace along the outer cylindrical surface of the cores.

Mechanical models to estimate the paleostress state from igneous intrusions [PDF]

open access: yesSolid Earth, 2018
Dikes and sills represent an important component of the deformation history in volcanic systems, but unlike dikes, sills are typically omitted from traditional paleostress analyses in tectonic studies.

Morphotectonics and paleostress analyses of Kutch area, Gujarat, India

open access: yesResults in Earth Sciences, 2023
The Kutch Rift Basin (KRB) is of great attention for its possible hydrocarbon reserve. In this context, geomorphologic and structural geologic studies of the onland basin area are crucial.

Influence of preexisting structures on the variation of neotectonic paleostress orientation in an area of the Southeastern Brazilian Margin

open access: yesBrazilian Journal of Geology, 2021
The Southeastern Brazilian Margin presents a NE-SW-striking structural framework, which is characteristic of the Neoproterozoic Ribeira Belt. Other important structural trends along the area are associated with E-W and NW-SE-striking structures, being ...

Paleostress magnitudes in folded sedimentary rocks [PDF]

open access: yesGeophysical Research Letters, 2011
Using Sheep Mountain Anticline (Wyoming, USA) as a case study, we propose a new approach to quantify effective paleo-principal stress magnitudes in the uppermost crust. The proposed mechanical scenario relies on a well-documented kinematic and chronological sequence of development of faults, fractures and microstructures in the folded strata ...

Geological characteristics of the boundary between Bolkardağı-Bozkır Units and the Ulukışla Basin and the structural evolution of the region, Central Taurides, Turkey

open access: yesBulletin of the Mineral Research and Exploration, 2021
The character of the boundary between the tectonic units in the Central Taurides and the Ulukışla Basin is controversial. The contact has been accepted as discordant or tectonic contact by different researchers.

FRACTURED TECTONICS OF CHROMITITES OF THE MAIN SARANOVSKOYE DEPOSIT (PERM KRAI)

open access: yesГеодинамика и тектонофизика, 2022
The Main Saranovskoe deposit is one of the largest chrome deposits in Russia. The chrome ore bodies are localized in the ultramafites of the Northern Saranovsky massif which has been studied since 1907. The research revealed that the massif is similar to

Cenozoic paleostress field of tectonic evolution in Qaidam Basin, northern Tibet

open access: yesOpen Geosciences, 2021
This article analyzes the stress fields in the Qaidam Basin since the entire Cenozoic using finite element numerical simulations. The stress fields are investigated by analyzing tectonic joints and the GPS velocity field in the basin.
